Bicyclist killed in collision with cement truck in San Marcos

SAN MARCOS  A 22-year-old man was killed Thursday when the bicycle he was riding collided with a cement truck in San Marcos, sheriff’s officials said.

The collision was reported about 9:35 a.m. at the intersection of Grand Avenue and South Las Posas Road.

Witnesses said the truck, which was heading north on Las Posas, stopped for a few seconds at the red light at the intersection, then turned right onto eastbound Grand Avenue, sheriff’s Deputy Agustin Rosas said.

The bicyclist was riding north on Las Posas. A preliminary investigation indicates he may have entered the intersection against a red light, the deputy said.

He was knocked to the ground, and may have been run over by the truck’s rear wheels, Rosas said.

The victim’s name was not yet released by the Medical Examiner’s Office. The truck driver was identified only as a 47-year-old man.
